Embodiment Construction

[0026] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0027] In this embodiment, the hybrid algorithm combining the dynamic programming method and the genetic algorithm is used to optimize the planning of the empty tool path of the urban rail chassis chute tool.

[0028] The working principle of the dynamic programming method: the basic idea of ​​the dynamic programming method is to first find the starting point of the first chute to be processed that is closest to the origin of the tool. When the current chute is processed, the tool needs to move from the end point of the processed chute. Continue processing to the starting point of the chute to be processed. The selection principle of the starting point of the chute to be processed is to find the s...

Abstract

The invention relates to the technical field of urban rail train manufacturing. The invention particularly discloses an urban rail underframe sliding groove cutter idle feeding machining path planningmethod. The method comprises the following steps: establishing a mathematical model of a cutter idle feed moving path; finding a starting point of the to-be-processed chute closest to the original point of the cutter; the cutter moving to the starting point of the nearest to-be-machined sliding groove from the cutter original point idle feed; the cutter moving from the starting point of the current to-be-processed chute to the end point of the current to-be-processed chute; completing machining of sliding groove, if the to-be-machined chute is not completely machined, machining the to-be-machined chute; finding a starting point of a to-be-machined chute closest to the end point of the current machined chute of the cutter; and the cutter moving to the starting point of the nearest to-be-machined sliding groove from the current machined sliding groove end point idle feed, conducting machining operation, and if all the to-be-machined sliding grooves are machined, the cutter moving to thecutter original point from the current machined sliding groove end point idle feed, and obtaining the numerical value of the cutter idle feed moving distance. According to the method, the cutter idlefeeding path is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail train manufacturing, in particular to a method for planning a machining path of an urban rail underframe chute tool in empty feed. Background technique [0002] At present, with the rapid development of urban rail transit, the application of light rail and subway is becoming more and more extensive, and the demand for urban rail trains is also increasing. Therefore, higher requirements are put forward for the processing efficiency of urban rail trains. As a part of the urban rail train body, the urban rail underframe chute is mainly used to install the equipment under the urban rail car. Due to the large number of urban rail underframe chutes that need to be processed, the large amount of removal, and the long cutting time of the tool, the processing efficiency of the urban rail underframe chute is low. Therefore, the cutting time of the tool can be optimized to improve the urban rail The pur...
